Question

I’m new to Apache Cayenne, and I’m trying out my first project. I’m attempting to use the Tools > Reengineer Database Schema feature of CayenneModeler to reverse engineer a SQL Server database.

I attempted to create a new “Saved DataSource”. I selected “org.apache.cayenne.dba.sqlserver.SQLServerAdapter” from its list of Adapters, and CayenneModeler automatically filled in the JDBC Driver field and added an example DB URL. I modified the DB URL, provided the username/password, clicked “Continue”, and then I get the following error:

Driver load error: com.microsoft.sqlserver.jdbc.SQLServerDriver

I assume this means that CayenneModeler does have a driver for sqlserver by default(?) But I don’t see a way to point CayenneModeler to any other drivers…

Any Cayenne experts out there know what I might be doing wrong? Is there a way to give CayenneModeler the driver it needs, assuming that is the problem? Or if a missing driver isn’t the problem, does anyone know what is?

Answer 1

The location for adding additional drivers is under Tools > Preferences > ClassPath (Windows) or CayenneModeler > Preferences… > Classpath (OSX).
